MACHINE FOR MAKING STEREOTYPE-EVIATRIX IMPRESSIONS.

SPECIFICATION forming part of Letters Patent No. 336,754, dated February 23,1886. Application filed April J0, 1835. Serial No. 162,858. (No modeLl To all whom it may concern:

Be it known that I, FRIEDRICH SCHREINER, of the city and county of Philadelphia, Pennsylvania, have invented a new and Improved Machine for Making StereotypeMatrix Impressions, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine for making impressions of single lines of types in paper or other soft material.

The invention consists of the combinations of parts, including their construction, substantially as hereinafter set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front View of my improved machine for making type-impressions. Fig. 2 is a cross-sectional view of the same on the line w m, Fig. 1. Fig. 3 is a plan View of one side piece of the same.

2 On the plate A two end uprights, B, aresecured, each provided with a Vertical recess, 0, and in its outer su rface with a vertical gui degroove, D, in which grooves D bars E slide having their lower ends united by a crosspiece, F, having a nut, G, through which a screw-spindle, H, passes, which has its upper end journaled in the underside of the plate A, and its lower end in an arm, J, projecting downward from the plate A, and having its 5 end connected by a rod, K, with the plate A, which arm and rod also serve as guides for the cross-piece F. A hand-wheel, L, is secured on the lower end of the said spindle H.

In the upper ends of the bars E a plate, M, is pivoted, and is provided on its top with two transverse lugs, N, having apertures for receiving a key, 0. The uprights B have shoulders P on which the plate M can rest.

A toothed angular piece, Q, is held in a 5 groove, It, in the front part of the plate A in such a manner that it can slide, and one end, Q, of the said piece Qprojects through aslot in the plate A, and has its lower end beveled. A lug, S, is formed on the cross-piece F, and serves to strike the beveled end Q of the piece Q, which is held by the spring S.

A plate, T, is pressed by-springs U upon the sheet of blotting or like paper, V, directly above the piece Q, the sheet V resting upon the plate A.

The operation is as follows: The cross-piece F is raised and the plate M rested on the shoulders P, as shown in dotted lines in Fig. 2. The type W, having shoulders, as shown in Fig. 2, are placed on the plate M, and held in place by the key 0, passed through the apertures in the lugs N. The cross-piece F is then moved downward, whereby the plat-e M and the type V on the same are swung into a vertical position, the faces of the types being at the bottom, and then the cross-piece is moved downward farther and the faces of the type pressed into the soft paper V. The crosspiece F is moved upward, the plate M moving into the position shown in dotted lines in Fig. 2.

The key 0 is withdrawn and the type removed, which can be done automatically-for example, by securing the type to cords connected with springs or weights in the typecase. Another line is set, an impression made, the type taken out and reset, &c., the paper being fed after each impression.

In the case shown the paper is fed by the toothed piece Q, which is moved in the reverse direction of the arrow at, when its end Q is struck by the lug S on the cross-piece F. Any other paper-shifting device may be used, and in place of the screw any other device may be used for raising and lowering thetypeholder.

The type for a single .line is set at a time and an impression of each line is successively taken, and then a stereotype cast of the impressed sheet is taken and used for printing in the usual manner.

By placing tissue-paper below the sheet upon which the impressions are made a copy of the impression made can be obtained at the same time that the impressions are being made upon the sheet. If desired, carbon paper can be used for obtaining the said copy.

Having thus described my invention,I claim as new and desire to secure by Letters Patent- 1. The combination, with sliding bars, of a type-holder pivoted between the same, and 00 mechanism consisting of a screw acting upon a cross-bar connected to rods secured to said sliding bars for pressing the type against a sheet, substantially as herein shown and described.

2. The combination, with side pieces having grooves upon the outer sides of said side pieces, of bars sliding in said grooves, and a type-holder pivoted to said bars, and guided in recesses in the side pieces, together with a screw acting upon a cross-bar secured to rods connected to the sliding bars, substantially as herein shown and described.

3. The combination, with side pieces, B, of the sliding bars E, the type-holder M, pivoted to the same, the cross-piece F, uniting the bars E, and a screw for working the side pieces up and down, substantially as herein shown and described.

4. In a type-impression-making machine, the type-actuating screw Whose nut carries a cross-bar, in combination with the paper-feeding contrivance consisting of the spring-seated toothed baractedupon by a projection of said cross-bar, and the plate T, substantially as and for the purpose set forth.
